Creating a Highly Available Transit Gateway Instance
You can create highly available (HA) Transit gateway instance during or after a Transit Gateway is created.
A Transit Gateway can have up to two highly available gateway instances. |
To create a highly available gateway instance during a Transit Gateway creation, see Creating a Transit Gateway.
To create a highly available gateway instance after a Transit Gateway is created, follow these steps.
-
In CoPilot, go to Cloud Fabric > Gateways > Transit Gateways tab.
-
In the table, locate the Transit Gateway and click the Edit icon on the right side of its row.
-
In the Edit Transit Gateway dialog, scroll down to the Instances section and click + Instance.
A new row is added.
-
From the Attach to Subnet dropdown menu, select the subnet in which to create the Transit gateway instance.
All gateway instances are created in active-active state and will forward network traffic in an event of tunnel failure between a Spoke VPC/VNet and Transit VPC/VNet. For best practice, each highly available gateway instance should be created in a different public subnet in a different availability zone, if available.
-
From the Public IP dropdown menu, select a public IP to allocate to the gateway instance or leave at Allocate New Static Public IP.

Click Save.
